Congenital tear duct obstruction

Congenital nasolacrimal duct obstruction is a classic condition that has been well investigated and is readily identified. The suggested sequence of treatment includes massage, irrigation, probing, insertion of a silicone stent and, finally, dacryocystorhinostomy. Because of the relatively frequent occurrence of duct obstruction in normal infants, family physicians need to be familiar with its diagnosis and treatment. If problems still exist after an adequate trial of conservative treatment, referral before six months of age is suggested.
